Yadav, a first-year student of Hotel Management, said: “When I was returning home some seniors, whom I didn’t recognise, took me to the other side of the road and forced me to eat a puri. Then they left me at the hostel.”

His father RPS Yadav said: “It is a case of ragging. I will report the matter to the college.”

DSP RN Mishra said: “A case under IPC Section 328 (Administering stupefying drug with intent to cause injury) against four unknown students has been lodged. Though the victim’s complaint didn’t mention ragging, we are probing that angle.”

Amity spokesperson Savita Mehta said: “Our initial probe found it wasn’t a case of ragging. It took place outside our campus.”
